Technical field
The present invention relates to a kind of reflector, have the manufacturing approach of the lighting device and the reflector of this reflector.
Background technology
In lighting apparatus, reflector is very common parts.In order to obtain higher optical efficiency, need on reflector, carry out coating.Usually use two kinds of technologies of vacuum-coating and anodic oxidation in the prior art.Yet, in the less and comparatively elongated reflector, especially be difficult to obtain the uniform coating of thickness through vacuum-coating technology in the bottom of reflector in size.In order to obtain the uniform coating of thickness, attempt amplifying the size of reflector in the prior art usually, but the size of product is restricted sometimes, does not have enough spaces to use this large-sized reflector.Certainly, anode oxidation process also is the solution of a routine, on the reflector of any shape and size, can obtain the uniform coating of thickness, yet the optical efficiency of the coating that is obtained by this technology is more much lower than vacuum-coating technology.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of reflector that is used for lighting apparatus, can on this reflector, obtain the uniform coating of thickness when carrying out vacuum-coating, thereby obtain higher reflectivity and good optical efficient.
The object of the invention is realized thus; Be that reflector comprises matrix and is arranged at least one reflection hole in this matrix, wherein, matrix comprises a plurality of minutes matrixes; Be provided with at least one sub reflector hole in each branch matrix; Matrix can be stacked each other in a plurality of minutes, and the sub reflector hole of each minute matrix is aimed at, and formed reflection hole.Through this frame mode; In vacuum-coating technology; The range difference of each position that steam flows to the reflecting surface of reflection hole is dwindled as far as possible, thereby has guaranteed the uniformity of thickness of coating to a great extent, thereby obtains higher reflectivity and good optical efficient.
According to a preferred design of the present invention, a plurality of minutes matrixes are stacked being parallel on the direction of optical axis each other, and each ratio of diameter and the degree of depth in sub reflector hole separately that divides matrix is more than or equal to 1.In this case; The distance difference that steam flows between each position of reflecting surface of reflection hole can not impact the uniformity of thickness of coating; Perhaps only cause MIN influence, thereby further guaranteed the higher reflectivity and the good optical efficient of reflector.
According to another design of the present invention, matrix was stacked on the direction perpendicular to optical axis each other in a plurality of minutes.In this design, need not the size of confirming to divide matrix according to the ratio of the diameter of reflection hole and the degree of depth, can directly arrive at the reflecting surface of reflector as long as guarantee vapor stream, thereby simplify manufacturing process, accelerated production efficiency.
Different according to the application purpose of lighting apparatus and function, but according at least one reflection hole of the present invention can be circularly also array ground or be arranged in the matrix linearly.
According to a design of the present invention, coating is carried out through vacuum-coating technology in the sub reflector hole.Vacuum-coating technology has the production efficiency height, and advantage with low cost uses this technology to reduce the production cost of reflector, has improved production efficiency.
According to a preferred design of the present invention, divide between the matrix to be fastened togather.This simple mechanical connecting structure makes assembling become unusual simple.
Another object of the present invention is to a kind of lighting apparatus with reflector of the above-mentioned type; Through using such reflector; Make this lighting apparatus have lower production cost; Can produce apace, make this lighting apparatus have higher reflectivity and good optical efficient again simultaneously.
In addition, the invention still further relates to a kind of method of making the reflector of the above-mentioned type, this method may further comprise the steps:
-a plurality of minutes matrixes are provided, wherein each divides matrix to be respectively arranged with at least one sub reflector hole;
-through vacuum-coating technology coating is carried out in the sub reflector hole;
-a plurality of minutes matrixes are stacked each other, form matrix, make the sub reflector hole behind the coating aligned with each other simultaneously, form reflection hole.
In a preferred design of method of the present invention, pile up a plurality of minutes matrixes in the direction that is parallel to optical axis, and when a plurality of minutes matrixes are provided, the diameter that makes each sub reflector hole separately of dividing matrix and the ratio of the degree of depth are more than or equal to 1.In this case; The distance difference that steam flows between each position of reflecting surface of reflection hole can not impact the uniformity of thickness of coating; Perhaps only cause MIN influence, thereby further guaranteed the higher reflectivity and the good optical efficient of reflector.
On direction, pile up a plurality of minutes matrixes perpendicular to optical axis.In this design, need not the size of confirming to divide matrix according to the ratio of the diameter of reflection hole and the degree of depth, can directly arrive at the reflecting surface of reflector as long as guarantee vapor stream, thereby simplify manufacturing process, accelerated production efficiency.
Should be appreciated that above generality is described and following detailed description is all enumerated and illustrative, purpose is in order to the present invention who requires to protect further explanation to be provided.
